The invention discloses a lighting control method, by setting the first target illumination value of the illumination sensor so that the illumination of the target area is the set illumination value. Later, at each time node, the system calculates the current second target illumination value of the illumination sensor, and then adjusts the brightness of the lamp so that the detected value of the illumination sensor reaches the second target illumination value. When the detected value of the illumination sensor reaches the second target illumination value, the illumination of the target area can be consistent with the set illumination value of the target area at this time. The present invention can make the target area to substantially maintain constant illumination during the illumination period.
